DESCRIPTION

The getopt() functions processes single-character switches with switch clustering. Pass one argument which is a string containing all switches that take an argument. For each switch found, sets $opt_x (where x is the switch name) to the value of the argument, or 1 if no argument. Switches which take an argument don't care whether there is a space between the switch and the argument.

Note that, if your code is running under the recommended use strict 'vars' pragma, you will need to declare these package variables with "our":

our($opt_foo, $opt_bar);

For those of you who don't like additional global variables being created, getopt() and getopts() will also accept a hash reference as an optional second argument. Hash keys will be x (where x is the switch name) with key values the value of the argument or 1 if no argument is specified.

To allow programs to process arguments that look like switches, but aren't, both functions will stop processing switches when they see the argument --. The -- will be removed from @ARGV.
